The increasing demand for advanced security and surveillance systems is significantly driving the growth of the infrared detector market. As security concerns grow globally, particularly in urban areas, the need for reliable monitoring solutions that function in low-light or no-light conditions has risen. Infrared detectors, which enable night vision and heat signature detection, have become essential components of modern security systems. Infrared LEDs and sensors have revolutionized the security and surveillance sector. Infrared illumination has become essential for low-light and nighttime surveillance cameras. Clear images of a scene can be captured in complete darkness. The use of IR LEDs in combination with image sensors has led to the development of intelligent surveillance systems that can detect intruders and track movement accurately. 

Additionally, artificial intelligence (AI)-driven facial recognition for access control and authentication purposes relies on IR sensors to improve accuracy and reliability by capturing unique facial features even in varying lighting conditions. A real-time example is the widespread adoption of infrared cameras in critical infrastructure protection, such as airports, power plants, and military bases, where continuous surveillance is vital. For instance, many high-security facilities now rely on infrared thermal cameras to detect unauthorized intrusions or suspicious activities in complete darkness, enhancing situational awareness and enabling faster response times. Moreover, home security systems increasingly incorporate infrared sensors to detect motion or heat signatures, alerting homeowners to potential break-ins or fire hazards. This surge in demand for 24/7 surveillance capabilities, coupled with the growing need for safety and prevention of criminal activities, is driving the infrared detector market forward.

Segmental Analysis

The Global Infrared Detector Market has been segmented based on Type, by Wavelength, by Materials, by Application, by End-User Industry.

Based on Type, this segment includes Thermal Infrared Detectors and Photonic Infrared Detectors. The Thermal Infrared Detectors segment dominated the global market in 2024, while the Photonic Infrared Detectors segment is projected to be the fastest–growing segment during the forecast period. Thermal infrared detectors are devices that measure temperature changes caused by infrared radiation. thermal detectors are to take advantage of the thermal effect to heat the detection element and cause heat transformation of some physical properties so that the IR radiation energy can be detected. Thermal detectors are frequently used in spectral regions which are difficult to access with photon detectors – in particular, for long-wavelength infrared light. Also, they are used where their low speed, moderate sensitivity and low dynamic range is no serious problem – for example, as optical power meters for lasers. The thermal detector works at room temperature. During its operation, there are temperature changes, which may have slow response, and a relatively low sensitivity compared with photon detectors.

Based on Wavelength, this segment includes Near-Infrared (NIR), Mid-Wavelength Infrared (MWIR), Long-Wavelength Infrared (LWIR). The Long-Wavelength Infrared (LWIR) segment dominated the global market in 2024, while the Mid-Wavelength Infrared (MWIR) segment is projected to be the fastest–growing segment during the forecast period. Long-wave infrared and technology get used in actual military operations. These cameras detect thermal emissions from people, animals, and vehicles when they emit heat at higher temperatures than the surrounding atmosphere. LWIR are less sensitive to thermal “noise” in the environment and thus are useful outdoors. They can “see” through foliage to detect heat emissions from enemy fighters, dangerous predators, or hidden vehicles. They can also detect roadway hazards in very dark conditions helping to avoid collisions with animals or vehicle damage by unexpected potholes or washed-out areas. Long-wave infrared or LWIR is a subset of the infrared band of the electromagnetic spectrum, covering the wavelengths ranging from 8µm to 14µm (8,000 to 14,000nm). This is the radiant heat that uncooled thermal imaging cameras see. Uncooled LWIR thermal imaging can be more affordable than cooled MWIR thermal imaging, as the sensors require fewer complex components and less ongoing maintenance.

Based on Materials, this segment includes Indium Arsenide (InAs), Indium antimonide (InSb), Indium Gallium Arsenide (InGaAs), Mercury-Cadmium-Tellurium (MCT), Vanadium oxide (VOx), Amorphous silicon (α-Si), Others. The Vanadium oxide (VOx) segment dominated the global market in 2024, while the others segment is projected to be the fastest–growing segment during the forecast period. Vanadium Oxide (VOx) is a material used in uncooled infrared detectors, known for its temperature-dependent resistance. It is widely used in microbolometers for thermal imaging and IR sensing. VOx-based detectors offer high sensitivity and cost-effectiveness. They play a key role in applications like automotive, healthcare, and security.

Based on Application, this segment includes Security and Surveillance, Gas Detection, Temperature Measurement, Others. The Security and Surveillance segment dominated the global market in 2024, while the Gas Detection segment is projected to be the fastest–growing segment during the forecast period. Infrared detectors play a crucial role in security and surveillance applications, offering advanced monitoring capabilities that are not reliant on visible light. These detectors can detect infrared radiation, which is emitted by objects based on their temperature, allowing them to "see" in complete darkness. In security systems, infrared detectors are commonly used in motion sensors, night-vision cameras, and perimeter surveillance systems to monitor areas even under low-light conditions or at night. They can detect human presence, vehicle movement, or unauthorized activities, providing real-time alerts to security personnel. The ability to detect heat signatures ensures enhanced surveillance, making it harder for intruders to evade detection. Additionally, infrared detectors are often integrated with thermal cameras, improving the effectiveness of security systems in diverse environmental conditions, including fog, smoke, and darkness.

Based on the End-User Industry, this segment includes Defense and Aerospace, Automotive, Healthcare, Industrial Manufacturing, Others. The Defense and Aerospace segment dominated the global market in 2024, while the Automotive segment is projected to be the fastest–growing segment during the forecast period. Infrared detectors play a critical role in the defense and aerospace industries, where they are used for a variety of advanced applications such as surveillance, targeting, navigation, and threat detection. In defense, infrared sensors are integral to night-vision systems, allowing military personnel to observe and track targets in low-light or complete darkness by detecting the infrared radiation emitted by warm objects. They are also used in missile guidance systems, where they help accurately track and lock onto targets based on their heat signatures. In aerospace, infrared detectors are used in various applications, including aircraft and spacecraft thermal imaging, detecting engines or structural malfunctions, and monitoring environmental conditions.
